在本文中，我们提出了一种在腹部记录中检测feg的新方法。该方法采用序列分析方法，利用干扰信号的先验信息来检测feg。我们的方法是在一组20个不同胎龄孕妇的腹部记录上进行评估的。将其在胎儿心率（FHR）检测成功率方面的性能与独立分量分析（ICA）进行了比较。结果表明，序列估计方法的FHR检出率为85%，优于ICA的60%。在低信噪比（SNR）的录音中，我们的方法的优越性能尤为明显。这表明我们的方法比ICA对FECG检测的鲁棒性更强。
In this paper, we propose a new method for FECG detection in abdominal recordings. The method consists of a sequential analysis approach, in which the a priori information about the interference signals is used for the detection of the FECG. Our method is evaluated on a set of 20 abdominal recordings from pregnant women with different gestational ages. Its performance in terms of fetal heart rate (FHR) detection success is compared with that of independent component analysis (ICA). The results show that our sequential estimation method outperforms ICA with a FHR detection rate of 85% versus 60% of ICA. The superior performance of our method is especially evident in recordings with a low signal-to-noise ratio (SNR). This indicates that our method is more robust than ICA for FECG detection.
